python - Django how to make form fields optional -


How to make the form field optional in the DNS?

My model, 

  class students (models.Model): first_name = model. Kharefild (max_long = 30) last_name = models.CharField (max_length = 40) email = Models.EmailField ()    
 
 
 assuming that you want to create  last_name  optional, you can use the attribute:  
  class.model: First_name = models.CharField (max_length = 30) last_name = models.CharField (max_length = 40, empty = true) Email = models.EmailField ()   
 Note that  CharField < On / code> and  TextField , you probably do not want to set  blank  (as for why to discuss See), but on other field types, you will need to, or you will not be able to save examples where the optional values ​​are omitted.
